ROCKET.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed November 21, 1916. "serial No. 132,531.

Be it known that. I, HENRY J. PAIN, a citi zen of the United States, residing in the borough of Manhattan, city, county and State of New York, have invented an Improvement in Rockets, of which the followin is the specification.

1y present invention relates to arocket, and particularlyto a signal rocket, although as will be understood, the pyrotechnic device made in accordance with this invention may be used merely for display purposes. Heretofore rockets-have 'been employed by the armies and navies of practically all countries for signaling purposes at night. The rockets so used have been eminently satisfactory when the signals intended to be given thereby have been observed, but a difficulty has been experienced in the use of such rockets in that when a signal is unexpected, as is the case in most instances, it is oftentimes unobserved, and therefore useless because no attention has been directed to it. The object of my present invention therefore, is to overcome this difiiculty and provide in a rocket together with means for creating varied colored lights for signal pu-r poses, a detonating char e which when fired will cause a report su ciently loud to be" heard for several miles, in order that for the intended purposes the signal cannot be very well unobserved, and the rocket made in accordance with my present invention will be hereinafter more particularly described. In the drawing, Figure 1 is the central longitudinal cross section of a signal rocket made in accordance with this invention. Fig. 2 is an elevation and partial section, illustrating a modified form of the invention.

Referring particularly to Fig. 1 of the drawing, it will be seen that in carryin out my invention, I employ a rocket ha y or case 10 which may be made of compressed cardboard, aper, or other similar suitable material. E5 is customary adjacent one end of the rocket the case may be provided with a tube 11 tq receive the stick which is ordi-v narily employed with rockets of the character to which thisinvention' relates. In a suitable position within the case, I employ a head or partition wall 12, made of clay or any other suitable material, and between the head 12 and the open or fuse end 13. ofthe rocket, the case is provided with the usual fire works material 14: having a. central lon.

being understood that so far as the display gitudinal, and referably tapering space 15 therein, in or or that when ignlted by a suitable'fuse, the gas generated by the fire works material may beejected through the open end of the rocket with such force that whenacting against the air itcauses the rocket to rise as is also customary.

Withinthe case 10, and suitably spaced from the head 12 I employ an additional partition wall or head 16 and between the heads 12 and 16 the case is filled With'a detonating charge 17 also composed of any material adapted whenfired to make an exceedingly loud report. This material for example may be a composition of aluminum,

sulfur, antimony and baryta, in suitable p1'0- portions, or may be ordinary gun-cotton, or

may be dynamite.

In the opposite end of the case, there is inserted a parachute 18 with disks 19 suitably attached thereto and displaying varied colored lights when ignited, these disks being formed of suitable substances to create carrying material to efiect the colored lights asshown and described in Letters Patent No. 617,539 granted to me Jan. 10, 1899 it or signaiing features of my present invention are concerned, there is nothing new over and above the pyrotechnic devices shown in the atents to which reference has just been ma e.

In order to eject the parachute and "the,- signaling devices carried by the same, the.

head or partition wall 16 is provided with a recess 20 in which a firing or ejecting charge 21 is placed, which upon being fired ejects the parachute and associated parts from the end of the rocket breaking the cap 22 and the cover 23 provided for-the normal protection of this end of the rocket before the same is used. The firing charge indicatedat 21 may be any composition well known in the art and used for this purpose, for example a composition of saltpeter, sulfur and charcoal.

Inorder that the parachute and associated parts may be ejected from the rocket in such a manner that the detonatin charge will'not interfere in any way with the visual effect of the lights carried by the parachute, I employ a relatively quick fuse 24, one end of which is carried into the inner end of the fire works material 1a and is lighted thereby after the fire works material has been burned to a suflicient extent to reach this end of the fuse. This, as will be understood,'will occur after the rocket has reached a predetermined height in the air. As shown in Fig. 1, the other end of this fuse 24: is embedded in the ejecting charge 21 so that almost simultaneously with this fuse 24c'becomin ignited, the ejecting charge 21 is fired an the parachute and associated parts are ejected from the rocket. ,Sufiiciently long after this occurs, four or five seconds for example, the fire works material burns .to its inner end, and ignites a relatively slow fuse 25 placed in and extending through the head 12 and communicating With the detonating charge 17 in order to fire the same, it being understood as hereinbefo're stated, when exploded this charge makes a sufficiently loud report to be heard for several miles, thereby directing the attention of those within hearing distance to the signal given by the rocket.

- As shown in Fig. 2, the head or partition wall 12 may be a solid structure and a rela tively slow fuse 26 placed in the partition wall 16in such a manner that one end of the same is in communication with the ej ecting charge 21 and the opposite end in contact with the detonating charge 17, so that in this structure the fuse firing the detonating charge is lighted by the ejecting charge which in turn is ignited b the fuse 24 in the same manner as that ereinbefore de scribed in connection with the form of the invention shown in Fig. 1.

Furthermore, be it understood that in the event of dynamite for example, .being employed as a detonating charge, it will be necessary to provide a suitable percussion cap in order to explode the charge.

I claim as my invention: 1. A rocket comprising a tubular body, a

. firing charge in one end thereof which when ignited causes the rocket to rise in the air, a transverse wall at the inner end of the firing charge, asecond transverse. wall spaced from the aforesaid transverse Wall and having a recess in one surface thereof, a detonating charge within the tubular body between the said transverse walls, a signaling device in the dpposite end of the tubular body, an ejecting charge beneath the signaling device and within the recess in the second aforesaid transverse wall, a fuse making communication between the firing charge and the said ejecting charge for the signal ing device, and a fuse extending through one of the said transverse walls for igniting the detonating charge.

2. A rocket con'iprising a tubular body, a firing charge in one end thereof which when ignited causes the rocket to rise in the air, a transverse wall at the inner end of the firing charge, a second transverse wall spaced from the aforesaid transverse wall and having a recess in one surface thereof, a detonating charge within the tubular body between the said transverse walls, a signaling device in the opposite end of the tubular body, an ejecting charge beneath the signaling device and within the recess in the second aforesaid transverse wall, a quick fuse extending from the inner end of the firing charge to the ejecting charge in the recess in the second aforesaid transverse wall, and a fuse extending through the first aforesaid transverse wall for igniting the detonating charge from the said firing charge.

Signed by me this 18th day of November,

' HENRY J. PAIN.
